Media V2 CTS Tests

Current folder comprises of files necessary for testing media extractor, media muxer, media codec SDK and NDK Api. These tests aims to test all codecs advertised in MediaCodecList, available muxers and extractors.

The aim of these tests is not solely to verify the CDD requirements but also to test components, their plugins and their interactions with media framework.

The test vectors used by the test suite is available at link and is downloaded automatically while running tests. Manual installation of these can be done using copy_media.sh script in this directory.

The test suite looks to cover sdk/ndk api in normal and error scenarios. Error scenarios are separated from regular usage and are placed under class *UnitTest (MuxerUnitTest, ExtractorUnitTest, ...).

Commands

$ atest android.mediav2.cts
$ atest android.mediav2.cts.CodecEncoderTest android.mediav2.cts.CodecDecoderTest
$ atest android.mediav2.cts.MuxerTest android.mediav2.cts.MuxerUnitTest
$ atest android.mediav2.cts.ExtractorTest android.mediav2.cts.ExtractorUnitTest

Features

All tests accepts attributes that offer selective run of tests.

Select codecs by name

To select codecs by name, codec-prefix can be passed to media codec tests to select one or more codecs that start with a given prefix.

Example: To limit the tests to run for codecs whose names start with c2.android.

atest CtsMediaV2TestCases -- --module-arg CtsMediaV2TestCases:instrumentation-arg:codec-prefix:=c2.android.

Example: To limit the tests to run for c2.android.hevc.decoder

atest CtsMediaV2TestCases -- --module-arg CtsMediaV2TestCases:instrumentation-arg:codec-prefix:=c2.android.hevc.decoder

Select codecs by type

To select codecs by type, mime-sel can be passed to media codec tests to select one or more codecs.

Example: To limit media codec decoder tests to mp3 and vorbis decoder

atest android.mediav2.cts.CodecDecoderTest -- --module-arg  CtsMediaV2TestCases:instrumentation-arg:mime-sel:=mp3,vorbis

Select extractors by type

To select extractors by type, ext-sel can be passed to extractor tests to select one or more extractors.

Example: To limit extractor tests to mp4 and webm types

atest android.mediav2.cts.ExtractorTest -- --module-arg  CtsMediaV2TestCases:instrumentation-arg:ext-sel:=mp4,webm

Select muxers by type

To select muxers by type, mux-sel can be passed to muxer tests to select one or more muxers.

Example: To limit muxer tests to mp4 and webm types

atest android.mediav2.cts.MuxerTest -- --module-arg  CtsMediaV2TestCases:instrumentation-arg:mux-sel:=mp4,webm
